Alta Zinc increases zinc resources in Italy ‘by a factor of more than 3.3x’
(Kitco News) - Alta Zinc (ASX: AZI) announced the updated mineral resource estimate for its Gorno zinc-lead-silver deposit in the northern Italian Province of Bergamo.
According to the company’s statement, the total updated indicated and inferred resources contain 530,000 tonnes of zinc at 6.8% ore grade, 140,000 tonnes of lead at 1.8% grade, and 8,040,000 ounces of silver at 32 g/t grade.
The company said that the total mineral resource tonnage has increased by a factor of 2.4x and the zinc grade has increased by 40% compared to the previous (2017) mineral resource estimate, leading to more than 3.3x the amount of zinc metal contained, of which more than 60% is in the indicated category.
Importantly, the company noted that Gorno’s mineralisation remains open in all directions outside of the mineral resource estimate with numerous step-out targets remaining to be drill tested from current underground development. Drilling remains on-going, focussing on mineralisation outside of the updated mineral resource estimate, and results will be released as assays become available.
Alta added that the updated mineral resource estimate will significantly underpin future mining and metallurgical studies, to fast-track the feasibility study and development of the Gorno project as one of Europe’s premier zinc-lead-silver deposits.
